Rayleigh-wood anomalies
WebRayleigh–Wood anomaly,14 found in metallic gratings with relatively wide slits. Although the Rayleigh–Wood anomaly is usually associated with the resonant excitation of an SP, the same effect is also present whenever there exists a sur-face mode, such as a slab waveguide mode in close proxim-ity to the grating.5 WebAs it will be seen in the following, Wood’s discovery immediately raised consid-erable attention and the fascination of many specialists of optics for the so-called Wood’s anomalies never died. Rayleigh proposed the first explanation for the exis-tence of the anomalies [2, 3]: an anomaly in a given spectrum occurs at a wavelength

Web1, and corresponding electric field on Fig. 2, 3). This is due to the fact that the first Wood anomaly (often referred as the Rayleigh Wood anomaly) always occurs at the cut off frequencies producing the extinction of all the propagative modes while the second -resonant- Wood anomaly does not happen for WebDiscovered by Wood in 1902, grating anomalies have fascinated specialists of optics for more than one century. Long after the first interpretation given by Rayleigh, Fano has …
WebThe Rayleigh Wood anomalies refer to an unexpected repartition of the electromagnetic energy between the several interference orders of the light emerging from a grating. Since Hessel and Oliner (Appl. Opt. 4, 1275-1297 (1965)), several studies have been dedicated to this problem, focusing mainly on the case of metallic gratings.
